Valmet Ultrafiltration Technology

A modular process for paper machine white water treatment

Colloidal substances, stickies and bacteria are among the main components that lead to runnability and efficiency losses in paper machine processes. Prevention of these reductions in performance can be achieved using a modular approach to whitewater treatment.

Valmet’s Ultrafiltration process is a solution for paper, board and tissue mills to produce colloid-free, bacteria-free, ultrapure water from white water. The main objectives are to reduce fresh water consumption, improve paper machine runnability, efficiency, and manage energy.

Valmet Ultrafiltration W

Valmet Ultrafiltration W is a solution for paper and board mills to produce colloidal, bacteria-free, ultrapure water from white water. The main targets are reducing fresh water consumption, improving paper machine runnability and production efficiency, and controlling the energy balance. 


Valmet Ultrafiltration C

Valmet Ultrafiltration C effluents containing coating color are concentrated without additional chemicals using ultrafiltration technology. The coating concentrate resulting from the process is returnable to the fresh coating color preparation line.
